Launching Applications

I am having major problems launching games and apps in evolution x i use the run linux mechassault exploit and i do what i am suppose to but when i launch them using flash fxp on my computer i get an error 21 they don't show up in the launch menu eitherso does anyone know a way around this

This how i set up my xbox
E:/XBMC/all the files

any ideas

 

the apps have to be signed with habbi code unless you use PBL

 

i use this dos program to do it called ezxbe or something and i don't think that worked either
